Not to pick on either of you specifically, but people get this wrong.
From the outside, the course of events is - product disappears from website with note that it is due to Gibson cease and desist. Gibson are bastards.
From the inside, the process is much more involved. The first thing that happens is a cease and desist letter. That gets shown to corporate counsel who present what the options are. Options include: choose to negotiate a license, choose to fight it out in court, choose to ignore it and hope it all goes away (but be prepared to go to court), choose to discontinue product.
None of us (unless someone here is counsel to Reverend or Gibson, and if so is probably bound by confidentiality) know what decisions were made internally. I can bet that the process took at least 3 months and probably took a year or more. An assessment of the ability to fight (cost as well as likely outcome) indicated that it was a poor option for any number of reasons including that perhaps they don't sell many. An assessment of the license negotiation process indicated that they could not raise the price of the item enough to compensate for the added cost. So the decision was to let the product line go thereby complying with the cease and desist.
On the inside, both sides made a series of decisions that resulted in a business decision to stop production.
